Hi,
I think it makes sense if it returns zero records because you are using
BooleanClause.Occur.SHOULD for each field, it means the term "open" should
occurs in all fields. but when you specify the field name in your query you
limit searching through that mentioned field.
as stated in Lucene javadoc the usage is:
String[] fields = {"filename", "contents", "description"};
int[] flags = {MultiFieldQueryParser.NORMAL FIELD,
MultiFieldQueryParser.REQUIRED FIELD,
MultiFieldQueryParser.PROHIBITED FIELD,};
parse(query, fields, flags, analyzer);

Hi,
I'm in need of your help.I was looking for how serach multiple fields
using Lucene,in one of the mailing list I found your solution
to the issue.
Its working perfectly but I need to pass query as field:query
If I pass only query its returing zero hits.
Below is code I'm using.
Please do help me out.
Thanking you,
Akbar Devani.
String fields [] = {"Name","Claim Update","Paid Indemnity","Paid
Expenses","O/S Indemnity","O/S Expenses",
"Incurred"," Status","Date / Added
by","Name","Paid Premium","Estimated","Premium
Status","File","Detail","Comment","Comments" };
BooleanClause.Occur[] flags = new
BooleanClause.Occur[fields.length];
Query query = null;
try
{
for (int i =0 ; i < fields.length ; i++)
{
flags[i]=BooleanClause.Occur.SHOULD;
}
query = MultiFieldQueryParser.parse(expression,
fields, flags, new StandardAnalyzer());
System.out.println("query:"+query.toString() );
//Log pasted below
}
catch (ParseException e)
{
log.error("Unable to make any sense of the query", e);
}
//Searching
try
{
IndexReader reader = IndexReader.open(ds.getRootPath
(SERVLET_INDEX));
IndexSearcher searcher = new IndexSearcher(reader);
Hits hits = searcher.search(query);
If I'm searching status:open its returing records where as if I'm
searching only open its returing zero.
